Boiler skimmer



1953 A. A. GIESEN BO ILER SKIMMER Filed March 16, 1951 INVEIYTOR.

tral portion localted immediately adjacent the upper surface ofthetrough H. The side portions cf thescreen 31 are inclined upwardly andoutwardly so that they are spaced above the trough edges and the unteredge portions 38 of the screen 31, in the oonstruction shown, arelocated closely adjacent the upper portion of frame members, and ascreen locasted above the trough, said screen being generally V-shapedin crosls section with the center of the v extending along adjacent (Eheoenter line 015 the top 015 the troughand its side portions locatedabove and spaced from dahe trough, the screen being wider the innerfaces of the floa.ts 30. In the constrction shown, the central portiono1 the screen 31 is secured to l7he inturned upper end flanges 40 of thetrough II. These flanges 40 are rein- :forced by sbrips 42 which may bewelded to their under faces and. screws 43 are passed through washers 45and through openings in the screen 31 anti are rthreaded into thereinforced flanges 40. The central portion of the screen 31 ispreferably unperforabed as shown in Figure 2 while the lateral portionsare perforated.

The operation of the skimmer construction shown will be apparent firomthe above description, the skimmer being installed in rthe holler andadjusted to fioat ab the surfaoe or submerged to a predetermined depthbelqw the surface and being located by means of the guide members I9.The spaced am]. elongated fioats 30 are of such a character as o reducetilting of the skimmer assembly due '00 fluctuation of suzrfacelevels inthe turbulent steam release zone as the water boils. The censtruction issuch that the skimmer will not bind against the vertical gu-ide membersI9 and will be free to tilt within necessary limits. The stop members 33are cylindrical in cross-seetion and present rounded surfacesfor.contact with the guide members I9. The spacing of the pauts is suchtha.t the ends cf the trough cannot erigag e-the guide members I9 tocause wear or' 130 bind against them.

While I have shown certain preferred. embodiments of my invention in theaccompanying drawings, these are d;o be understood to be illustrativeonly as the construction may be varied to meet different conditions andrequirements and I contemplate such modifications as come within thespirit and scope of Hohe appdended claims.

In the claims:

1. In a skimmer for removing suspended and dissolved solids from fiuidsin boilers and the like, anelongated trough, a conduit leacling from thelower portion of the trough, spaced conniacting membersextending fromeach end of the trough, cross fcrame members connected to the ends ofthe connectlng members, saicl cross frame members being longerthan thewidth of the trough, elongated float members extending parallel with andspaced from the edges of the trough and connected ad: each end to thecross frame members and a screen located above the brough, said screenbeing generally V-shaped in cross section with the eenter of the Vextending along adjacent the center line of the top of the trough andi1ts side portions located above and. spaced from the trough.

2.In a skimmer for removing suspended anal dissolved solids from fluidsin boilers and the like, an elongated brough, a conduit leading from thelower portion of the trough, spaced cannecting members extending fromeach end of the trough, cross frame members connected 120 the ends cfd:he connecting members, said cross frame members being langer than thewidth of the trough, elongated fioat members extendlng parallelwith andspacedfrom the edges of the trough and connecteiatzeach'end to the crossthan the trough and. extending adjacent the fioats'.

3; In askimmer for removing suspended and dissolved solids from liquidsin bo-ilers and the like, an elongated trough, a flexible conduitleading from the lower portion of the trough, spaced oonnecting membersexbending from each end of -'he trough,cross frame members connected 120the ends 'of the spaced ccnnectirlg members, floats connected 110 thecross frame members, a

pair ofspaced guide members adapted 420 be sespaced connec-ting' membersand the cross faame members, the guide members being spaced apart adistance greater than the length of the trough, and stop membersextending between the comnecting members and locaxted between the guidemembers and cross frame members, the relative spacing being such thatthe stop members prevent the guide members from contacting the end.s 0fthe trough.

4.In a floating skimmer for removing suspended and dissolvecl solidsfrom liquids in beilers and the like, an elongated dzrough, a flexibleconcluit l'eading Irom the lower portion of the trough, spacedconnecting members extending from each end of the trough, cross framemembers connected. ehe ends of the spaced connecting members, said crossframe members being longer than the wid bh of the trough, elongatedfioats on each side of the trough and spaced therefrom, the ends of thefi0ats being adjustably connected 120 the cross frame members, a screensecured adjacent the upper face of the trough with its lateral portionsinclined upwardly and extending above and spaced from the troughandadjacent the fioats, a pair 01 spaced guide members adapted tobesecured to a heiler structure, one of such guide members extendingvertically in the space at each end of the trough between the trough,the spaced connecting members and the cross frame members, the guidemembers being spaced apart a distance greater than the length of thetrough, and stop membecvs extending betvveen the connecting members andlocated between Nahe guicle members and cross frame members, therelative spacing being such (hat the stop members prevent the guidemembers from contacting the ends of the trough.
